10. A thin light insulating rod of length / is free to rotate in a horizontal
plane about a vertical axle passing through its centre, Two small balls
each of masss m and charge q are affixed at the ends of the rod. This
assembly is symmetrically placed between eylindrical poles N and S of
an electromagnet that have established a uniform vertical magnetic
ield of induction Bo. The electric supply to the coils of the electromagnet
is switched off. Find the angular velocity acquired by the rod long time
after the magnetic field vanishes. Assume that the field was only
between the poles of the magnet. A, 9d2B0
